FAUCET FOR SHEET-METAL VESSELS.

SPECIFICATION forming part of Letters Patent No. 234,710, dated November 23, 1880.

I Application filed November 1, 1879.

the faucet in the can without the aid of other tools; and the invention consists in certain details of construction which are fully set forth below.

The drawing accompanying this specification, and forming a part thereof, shows, in section, a can to which my improvement has been applied.

` .Referring to said drawing', A represents the can, which may', of course, be of any size or shape.

B is my peculiar faucet, whichv differs from other faucets in respects which Iwill now set forth. The end which is inserted within the can is provided with a sharp metal point, C, designed to pierce the can, which it may be made to do by the exertion ot' a little force. This point is made tapering' and with smooth sides, so its insertion may not be impeded,

and after puncturing it is crowded down intothe can until the screw-thread D upon the exterior of the faucet-barrel engages with the surroundingI metal of the can, from which time the faucet should be turned until the eX.- terior swell or abutment, E, is drawn tightly against the can. When this has been done the faucet is ready for use.

In some cases the faucet may be brought home with the nozzle pointing in some direction other than downward, and inasmuch as the material of the can does not permit latitude as to the point where the screwing in of the faucet may cease, as would a wooden vessel, I attach the nozzle F so it may be swung to the proper position for use, no matter where the inserting operation may leave it. This swiveling attachment of the nozzle is, by means of a 1,'n,f, passing from the nozzle into an annular groove, f', around the eXterior of the faucet-barrel.

Inasmuch as the puncturing-point closes the inner end of the faucet-channel, I provide back of the puneturing-point, and preferably in advance of the screw-thread, an appropriate number of openings, I), which admit the contents of the can to the main channel m of the faucet.

To prevent loss of the contents by leakage .through the joint formed between the screwthread and the can, I insert within the bulb E an annular washer, G, of rubber or other suitable material. There is thus formed eX- terior to the can a chamber, H, into which all such leakage must nd its way, and from that chamber it is conducted to the main passagem by lateral passages o, ot' which there should be a suitable number.

In inserting the faucet a better opening is sometimes made by working it right and left as it is being crowded up to the point where the screw takes hold. In starting the screw, also, it is well to hold the nozzle a little out ot' the perpendicular, as the screw is more apt to take hold then. The metal will be turned under by the forcing in of the utensil, as at a.

It will be understood that the parts of the apliraratus which come in contact with the liquid of the vessel should be made of some metal which will not injuriously affect the liq nid, or be coated with some such metal.

What I claim, and desire to secure by Let ters Patent, is-

1. The faucet for sheet-metal vessels having a puncturing-point, a screw-thread back of the point, and an exterior swell or abutment, E, the screw-thread extending back of the bearing-surface of the abutment or its interposed washer, whereby the abutment may be tightened against the vessel by the engagement of the thread with the side ot' the vessel, and external tightening devices are dispensed with, substantially as specified.

2. A faucet for sheet-metal cans and vessels provided with a pnncturing-point for puncturing the vessel, an exterior screwthread engaging with the metal of the vessel,`
